ʻO ka hoʻāʻo non-destructive ka hoʻohana ʻana i nā waiwai acoustic, optical, magnetic a me ka uila, me ka ʻole e hōʻino a hoʻopilikia paha i ka hoʻohana ʻana i ka mea ma lalo o ka manaʻo o ka hana o ka mea e nānā ʻia, e ʻike ai i ke ola ʻana o nā hemahema a i ʻole inhomogeneities i ka mea. e nānā ʻia, e hāʻawi i ka nui o nā hemahema, kahi o nā hemahema, ke ʻano o ka helu o ka ʻike a pēlā aku, a laila e hoʻoholo i ke kūlana ʻenehana o ka mea e nānā ʻia (e laʻa, kūpono a kūpono ʻole paha, koena ola. a pēlā aku) nā ʻano loea a pau o ka huaʻōlelo laulā.
Hoʻohana pinepine ʻia nā ʻano hoʻāʻo ʻole luku: Ultrasonic Testing (UT), Magnetic Particle Testing (MT), Liquid Penetration Testing (PT) a me X-ray Testing (RT).
Ka ho'āʻo ultrasonic
ʻO UT (Ultrasonic Testing) kekahi o nā kaʻina hoʻāʻo ʻole luku i ka ʻoihana. ʻO nā hawewe kani kani i loko o ka mea i loaʻa i nā hemahema, ʻike ʻia kahi hapa o ka hawewe kani, hiki i ka transmitter a me ka mea hoʻokipa ke kālailai i ka nalu i hōʻike ʻia, hiki ke ana i nā hemahema. A hiki ke hōʻike i kahi a me ka nui o nā hemahema o loko, e hoʻoholo i ka mānoanoa o ka mea.
Nā pōmaikaʻi hoʻāʻo ultrasonic:
1, nui ka hiki ke komo, no ka laʻana, i ke kila i ka hohonu ʻike pono a hiki i 1 mika a ʻoi aku paha;
2, no nā hemahema ʻano mokulele e like me nā māwae, interlayers, etc., ka ʻike ʻana i ka naʻau kiʻekiʻe, a hiki ke hoʻoholo i ka hohonu a me ka nui o nā hemahema;
3, nā lako māmā, ka hana palekana, maʻalahi e ʻike i ka nānā ʻana.
Nā hemahema:
ʻAʻole maʻalahi ka nānā ʻana i ke ʻano paʻakikī o ka mea hana, pono ke ʻano o ka maʻalahi o ka ʻili i nānā ʻia, a koi ʻia ka mea hoʻohui e hoʻopiha i ke āpau ma waena o ka probe a me ka ʻili i nānā ʻia e hōʻoia i ka hoʻopili ʻana i ka acoustic.
Nānā Mākēneki
ʻO ka mea mua, e hoʻomaopopo kākou i ke kumumanaʻo o ka nānā ʻana i nā ʻāpana magnetic. Ma hope o ka magnetization o nā mea ferromagnetic a me nā mea hana, ma muli o ke ʻano o nā discontinuities, nā laina magnetic o ka ikaika ma ka ʻili o ka mea hana a kokoke i ka ʻili o ka distortion kūloko, a hoʻoulu i kahi māla leakage, adsorption o ka pauka magnetic i hoʻopili ʻia i ka ʻili. o ka mea hana, e hana ana i ike maka ma ke kukui kupono, pela e hoike mai ai i ka wahi, ke ano a me ka nui o ka hoopau ana.
ʻO ka hoʻohana ʻana a me nā palena o ka nānā ʻana i nā ʻāpana magnetic:
1, kūpono ka ʻike ʻana i nā hemahema o nā mea ferromagnetic a kokoke i ka ʻili me ka liʻiliʻi liʻiliʻi a me nā āpau haiki i paʻakikī ke ʻike maka.
2, hiki i ka nānā ʻana i nā ʻāpana magnetic ke ʻano o nā hihia o ka ʻike ʻana i nā ʻāpana, akā he ʻano like ʻole o nā ʻāpana e ʻike ʻia.
3, hiki ke loaʻa nā māwae, inclusions, hairline, keʻokeʻo kiko, peluʻi, anu hoʻokaʻawale a me ka wehe a me nā hemahema.
4, ʻaʻole hiki i ka nānā ʻana i ka ʻāpana magnetic ke ʻike i nā mea kila kila austenitic a me nā welds i hoʻopaʻa ʻia me ka austenitic stainless steel welding electrodes, a ʻaʻole hiki ke ʻike i ke keleawe, aluminika, magnesium, titanium a me nā mea non-magnetic ʻē aʻe. No ka ʻili o nā ʻōpala pāpaʻu, kanu ʻia nā lua hohonu a me ke kihi o ka mea hana ma lalo o 20 ° delamination a me ka pelu ʻana he paʻakikī ke loaʻa.
ʻIke i ke komo ʻana o ka wai
ʻO ke kumu kumu o ka ʻike ʻana i ke komo ʻana o ka wai, ua uhi ʻia ka ʻili o ka ʻāpana me nā dyes fluorescent a i ʻole nā kala kala, i loko o kahi manawa ma lalo o ka hana o ka capillary, hiki i ka wai komo ke komo i loko o nā hemahema o ka wehe ʻana; ma hope o ka wehe ʻana i ka wai komo nui ma ka ʻili o ka ʻāpana, a laila uhi ʻia me kahi mea hoʻomohala ma ka ʻili o ka ʻāpana.
Pēlā nō, ma lalo o ka hana a ka capillary, e huki ka mea hoʻomohala i nā hemahema i ka paʻa ʻana o ka permeate, e hoʻi hou i ka mea hoʻomohala, i kekahi kumu kukui (ultraviolet kukui a i ʻole ke kukui keʻokeʻo), e hōʻike ʻia nā hemahema i nā traces permeate, ( ʻulaʻula melemele-'ōmaʻomaʻo a i ʻole ʻulaʻula ʻulaʻula), i mea e ʻike ai i nā hemahema o ka morphology a me ka hāʻawi ʻana o ka mokuʻāina.
ʻO nā pōmaikaʻi o ka ʻike ʻana i ke komo ʻana:
1, hiki ke ʻike i nā ʻano mea like ʻole;
2, he kiʻekiʻe koʻikoʻi;
3, he intuitive ka hōʻike, maʻalahi e hana, haʻahaʻa nā kumukūʻai ʻike.
A ʻo nā hemahema o ka hoʻāʻo ʻana ʻo:
1, ʻaʻole kūpono no ka nānā ʻana i nā mea hoʻoheheʻe porous i hana ʻia i nā mea hana a me nā mea hana ʻili;
2, hiki ke ʻike i ka hoʻāʻo ʻana i ka ʻili o nā hemahema, paʻakikī ke hoʻoholo i ka hohonu maoli o nā hemahema, a no laila paʻakikī ke hana i ka loiloi quantitative o nā hemahema. Hoʻopilikia pū ʻia nā hopena ʻike e ka mea hoʻohana.
Loaʻa i nā lako wili Xinfa nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe a me ke kumu kūʻai haʻahaʻa. No nā kikoʻī, e kipa:Welding & Oki Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Nānā X-ray
ʻO ka hope loa, ʻo ka ʻike hihi, no ka mea, e nalowale nā kukui X ma o ka mea irradiated, ʻokoʻa nā mānoanoa like ʻole o nā mea like ʻole ma kā lākou absorption rate, a ua kau ʻia ka ʻino ma kēlā ʻaoʻao o ka mea irradiated, no ka mea, ʻo ka ikaika o nā kukuna. ʻokoʻa a hana i ke kiʻi kūpono, hiki ke hoʻokumu ʻia nā loiloi kiʻiʻoniʻoni ma ke kiʻi e hoʻoholo ai inā he mau hemahema i loko o ka mea a me ke ʻano o nā hemahema.
ʻO ka hoʻohana a me nā palena o ka ʻike hihi:
1, ʻoi aku ka maʻalahi o ka ʻike ʻana i nā hemahema volumetric, maʻalahi ke ʻike i nā hemahema.
2, maʻalahi ka mālama ʻana i ka ray negative, aia ka traceability.
3, ʻike i ke ʻano a me ke ʻano o nā hemahema.
4, ʻaʻole hiki i nā hemahema ke ʻimi i ka hohonu hohonu o nā hemahema, ʻoiai ka ʻike ʻana o ka mānoanoa palena ʻole, pono e hoʻouna pono ʻia ka mea maikaʻi ʻole e holoi, a loaʻa i ke kino o ke kanaka kekahi pōʻino, ʻoi aku ke kumukūʻai.
I ka pōkole, ultrasonic, X-ray flaw detection ua kūpono no ka ʻike ʻana i nā hemahema o loko; kahi kani ultrasonic no ka oi aku ma mua o 5mm, a me ke kinona o na mahele maʻamau, X-ray hiki ole ke huli i ka hohonu kanu o na defects, radiation. He kūpono ka ʻike ʻana i nā hemahema ma ka ʻili o nā ʻāpana; i waena o lākou, ua kaupalena ʻia ka ʻike ʻana i nā mea hoʻoheheʻe magnetic i ka ʻike ʻana i nā mea magnetic, a ua kaupalena ʻia ka ʻike hemahema i ka ʻike ʻana i nā hemahema hāmama ma ka ʻili.
